Effectiveness of polymers on improving the fluid loss of Bentonite used in geosynthetic clay liners
Effectiveness polymers improving fluid loss Bentonite used geosynthetic clay liners
2012/3/30
Geosynthetic clay liners (GCLs) are generally used in engineering projects due to their low hydraulic conductivity with water. The bentonite component contributes hydration-induced swelling and impart...
Molecular Simulations of Montmorillonite Intercalated with Aluminum Complex Cations. Part II: Intercalation with Al(OH)3-Fragment Polymers
Al-Cation Gibbsite-like Polymers Intercalation Molecular Simulations Montmorillonite
2011/12/8
Abstract: The Crystal Packer module in the Cerius2 modeling environment has been used to study the structure of montmorillonite intercalated with Al(OH)3-fragment (gibbsite-like) polymers. Basal spaci...
The Effect of Added Polymers on n-Butylammonium Vermiculite Swelling
Interlayer Spacings Neutron Diffraction Osmotic Swelling Phase Transitions Polymers Vermiculite Gels
2011/12/22
Abstract: A 4-component clay-polymer-salt-water system was studied by neutron scattering. The clay-salt-water system consisted of n-butylammonium vermiculite, n-butylammonium chloride and heavy water,...
Reaction of OH-Al Polymers with Smectites and Vermiculites
Smectite Vermiculite OH-Al Pillared clay
2011/12/30
Five montmorillonites, one hectorite, and two vermiculites were treated with OH-Al solutions containing rapid- and slow-reacting polymers of similar concentrations. With all smectites, both rapid- and...
Reduction of the Cation-Exchange Capacity of Montmorillonite by Take-Up of Hydroxy-Al Polymers
Cation-exchange capacity Hydroxy-Al polymer Interlayer Montmorillonite Smectite
2012/1/12
The cation-exchange capacity (CEC) of Na-Al- and Ca-Al-montmorillonite after neutralization with NaOH or Ca(OH)2 was studied at three Al levels: 10, 25, and 50% of the CEC. Hydroxy-Al polymers were ef...
